f(n)=4 f (n-1) if n > 1

A)

5, 20, 80, 320

B)

5, 14, 60, 236

C)

5, 25, 100, 400

D)

5, 25, 125, 625


Given the recursive formula below, what are the first 4 terms of the sequence?
f(n)= f (1) = 17
f(n)=f(n-1)-2 if n>1

A)

17, 13, 9, 5

B)

17, 19, 21, 23

C)

17, –6, –3, 0

D)

17, 15, 13, 11

Answer 1

`\begin{gathered} f(n)=f(n-1)+4 \\ so \\ f(1)=3 \\ f(2)=3+4=7 \\ f(3)=7+4=11 \\ f(4)=11+4=15 \end{gathered}`

answer: C.
